Technical details

The sshd-ldap component fails to properly escape LDAP filter metacharacters, allowing LDAP injection attacks. An unauthenticated remote attacker can authenticate by using "*" as both username and password, bypassing credential validation. The vulnerability affects versions 1.2.0 through 2.19.0 and 3.0.0-M1 through 3.0.0-M5; it is fixed by proper RFC 4515 escaping of filter parameters in versions 2.20.0 and 3.0.0-M6.

Affected products

Apache MINA SSHD 1.2.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5
